Multiple services to run on a container or multiple containers Docker?

General

I have a container with a Laravel application that is used for development.

So I don’t use an apache image, only a php 5.6 one. The process that keeps the container alive from not stopping is

php artisan serve --host=0.0.0.0

and this is also the command that start start the Laravel application server.
The application folder is mounted locally on my computer.

For my project I also need to run in my app root folder:

gulp watch
php artisan run:command
php artisan command:runServer 8282

So where and how can I run those commands? Should I create container for each command?
